For completeness, export process actually inherits some buffer local values. See `org-export--generate-copy-script', in particular ;; Copy specific buffer local variables and variables set ;; through BIND keywords. ,@(let ((bound-variables (org-export--list-bound-variables)) vars) (dolist (entry (buffer-local-variables (buffer-base-buffer)) vars) (when (consp entry) (let ((var (car entry)) (val (cdr entry))) (and (not (memq var org-export-ignored-local-variables)) (or (memq var '(default-directory buffer-file-name buffer-file-coding-system)) (assq var bound-variables) (string-match "^\\(org-\\|orgtbl-\\)" (symbol-name var))) ;; Skip unreadable values, as they cannot be ;; sent to external process. (or (not val) (ignore-errors (read (format "%S" val)))) (push `(set (make-local-variable (quote ,var)) (quote ,val)) vars)))))) So basically, it copies all Org related variables, default directory, buffer-file-name buffer-file-coding-system and any variable defined as a BIND keyword, provided their value is `read'-able (e.g., not a hash table).
